Impulses, or electrical signals, travel through both the left and right chambers of your heart to make it pump. But if the pathway is blocked, the impulses may move slower than normal or irregularly.

Left bundle branch block (LBBB) is a type heart block. It results from a problem with the electrical conduction system that enables the heart to beat. It may cause no symptoms, but an ...

Dallas, TX - Left bundle-branch block (LBBB) on the electrocardiogram identifies a subset of patients with NYHA class 1-2 heart failure and a wide QRS complex who gain the most from cardiac ...

LBBB is linked to electrical abnormalities, causing inefficient heart pumping, dilation, and systolic dysfunction. The study found LBBB associated with increased heart failure risk, surpassing other ...

Among patients with mild heart failure, only those who have left bundle branch block (LBBB) stand to gain better long-term survival from receiving cardiac resynchronization therapy (CRT) in addition ...

In order for your heart to beat properly, your heart’s tissue conducts electrical impulses throughout your heart muscle in a regular pattern. This electrical impulse causes the upper chambers (atria) ...
